Yamaha Yz450F

The Traction Control System communicates wheel slip to the ECU, tuning the engine to maintain ideal rear wheel traction. Three levels can be selected: HIGH, LOW or OFF. The Launch Control System continues to implement traction control and features an rpm limiting setting, which can be adjusted in 500 rpm increments between 6,000 rpm and 11,000 rpm. Both systems are controlled through the Yamaha Power Tuner App.
